Check the cables for lose connections, and if it still doesn't work, I'd just buy a new one like Fartin said.
It's not really worth it to demand a new one through warranty or whatever because you have to e-mail them over in Asia and wait for them to translate your e-mail, then you get some broken English thing sent back to you and you're all like, WTF? Then they finally mail you a voucher for a new one 10 weeks later and in the mean time you're sitting with a broken CD-ROM that you can't use.
